Automatic Lossless Image Compression

We have a robot – his name is optimizerbot and he will look through your themes daily to find any PNG or JPEG images that can be losslessly compressed and automatically commit the compressed version to your theme’s subversion repository. We have found that about 80% of existing images in VIP themes can be compressed this way, saving precious bytes and providing a better user experience, especially on slower networks, like 3G.

Here is an example of what the commit message will look like:

The first column is the file name, second column is the old file size in bytes, third column is the new file size in bytes, and the last column is the % saved.
